Q: Computer overheats and kernel_task is the culprit, but how do I fix it?
My computer always overheats when I use my television as a monitor.
The Trifecta of Doom™ is: streaming video, outputting HDMI to my TV (which kicks in the AMD Radeon graphics), and having the power cord plugged in. When this happens, the video gets really stuttery, and, according to Activity Monitor, kernel_task starts hogging 500%+ of the CPU. The fans go crazy, the computer starts to slow down, it is a nightmare. Any ideas on a fix?
